AuctraAuthority & delegation foundations
Narrowing permissions in agent hierarchies
Sub-agents must inherit subsets of parent authority—never broader scopes. Design narrowing rules for orchestrator and worker agents with Auctra delegations.

What is permission narrowing for agents?
Permission narrowing means each agent in a hierarchy receives a subset of its parent's delegated authority—never additional tools, higher spending caps, or longer expiration.
Orchestrators may plan across systems; workers should execute within tighter bounds. Without narrowing, multi-agent graphs become privilege escalation paths.
Auctra delegations encode action types and limits per agent so child grants can be validated against parent scope at issuance and at evaluateAction time.
Narrowing framework (5 layers)
Parent grant inventory — document maximum authority the orchestrator holds from its sponsor.
Child scope design — list which action types and limits each worker actually needs.
Issuance validation — reject child delegations that exceed parent bounds.
Runtime evaluation — evaluateAction on the acting agent with its own delegation record.
Audit proof — retain parent and child delegation IDs on every decision for reconstruction.
What to deploy first with Auctra
Register orchestrator and workers separately with sponsors. Issue parent delegation first; child delegations only within parent limits.
Block wildcard action types on workers. Renew parent before child to avoid orphaned grants.
Key takeaways
- Permissions only narrow at each hop—industry consensus for safe multi-agent systems.
- evaluateAction on the acting agent preserves accountability per execution boundary.
- Parent delegation expiry should cascade to children automatically.
Implementation checklist
- Map orchestrator vs worker action types in an architecture diagram.
- Issue parent delegation with explicit maximum limits.
- Create child delegations as strict subsets.
- Evaluate at worker boundaries with distinct agent IDs.
- Alert when a child grant request exceeds parent scope.
People also ask
- Why must agent permissions narrow?
- To prevent orchestration layers from accidentally amplifying authority beyond what a human sponsor approved.
- How does Auctra enforce narrowing?
- Delegations are per-agent with explicit limits; evaluateAction checks the acting agent's active grant, not inherited API keys.
- What if a worker needs temporary broader scope?
- Issue a new delegation with sponsor approval or route the action through human review—never silently widen child grants.

Model a narrowed worker delegation
Issue a parent grant, then a child grant inside its limits—and evaluate from the worker.

- In Agents registry (https://console.auctra.tech/console/agents), register agents and assign sponsors.
- Issue worker delegation with reduced action types and lower limits.
- Call evaluateAction from the worker and confirm audit shows both delegation IDs.
